Installation

Examples:

Simple usage with default props

import React, { Component} from 'react';
import Overlay from 'react-native-modal-overlay';

export default class OverlayExample extends Component {
  state = {
    modalVisible: true, 
  }
  
  onClose = () => this.setState({ modalVisible: false});
  
  render() {
    return (
        <Overlay visible={this.state.modalVisible} onClose={this.onClose} closeOnTouchOutside>
          <Text>Some Modal Content</Text>
        </Overlay>
    );
  }
}

Complex usage with render props

Use case: For Example you have a cross button inside your modal and you want to close the modal when the button is pressed. This can be done by calling hideModal argument in the render props instead of calling onClose. Refer to the example below:

import React, { Component, Fragment} from 'react';
import Overlay from 'react-native-modal-overlay';

export default class OverlayExample extends Component {
  state = {
    modalVisible: true, 
  }
  
  onClose = () => this.setState({ modalVisible: false});
  
  render() {
    return (
      <Overlay visible={this.state.modalVisible} onClose={this.onClose} closeOnTouchOutside
        animationType="zoomIn" containerStyle={{backgroundColor: 'rgba(37, 8, 10, 0.78)'}}
        childrenWrapperStyle={{backgroundColor: '#eee'}}
        animationDuration={500}>
        {
          (hideModal, overlayState) => (
            <Fragment>
              <Text>Some Modal Content</Text>
              <Text onPress={hideModal}>Close</Text>
            </Fragment>
          )
        }
      </Overlay>
    );
  }
}

Note that the whole hideModal and internal state of the component is being passed as arguments to the render prop.
